- An undivided multilane highway segment has the following characteristics: • Six lanes (three lanes in each direction); Lane width of 11 ft; • Speed limit of 45 mph; Right shoulders is 4 ft wide; • There are approximately 25 access points over a 2-mile section of this roadway, in each direction. Calculate the FFS at this highway section and then determine the level of service (LOS) when the flow rate is 1100 pc/h/In. (Write the answer for the LOS in the box below).Given that (40 vehicles) pass during roadway section in ( 60 sec.) and travel length (1000 m). What is density, flowrate, spacing and headway.QUESTION 8 If the free flow speed of the highway is measured in the field, you apply adjustments for lane width, total lateral clearance, type of median, and access density to estimate free flow speed. O True False
- Given the following data: SSD = 430’ G = +3% Tpr = 2.5 sec Will the speed/velocity be acceptable if the road is generally posted at 30kph? Why or why not?Traffic volume is 2578 veh/hr with 687 vehicles arriving in peak 15 minutes.There are tow lanes, 12 percent trucks(30/70 split for SUT/TT), the length of the road is 1.8 miles long with a 3.5 percent grade. calculate the analysis flow rate?A section of highway has a speed–flow relationship of the form q = au2 + bu, where q is the traffic flow in veh/h, u is the space-mean speed of traffic in mi/h, and a and b are unknown parameters. It is known that at capacity (which is 3100 veh/h) the spacemean speed of traffic is 28 mi/h. Determine the speed when the flow is 1500 veh/h and the free-flow speed.
- Give the Greenberg's speed-density relation equation for the following traffic data.The space mean speed (kmph) and density (vehicles/km) of a traffic stream are linearly related. The free flow speed and jam density are 80 kmph and 100 vehicles/km respectively. The traffic flow (in vehicles/h, up to one decimal place) corresponding to a speed of 40 kmph is SIIRDEDramps within 3 miles upstream and downstream of the segment midpoint. It is on rolling terrain with 10% heavy vehicles and is operating at capacity with a peak-hour factor of 0.9. If the road is expanded to four 11-foot lanes with a 2-foot right shoulder, and traffic after the expansion is projected to increase by 10% with the same heavy vehicle percentage and peak-hour factor, what is the new LOS and estimated density? P-22 Chapter 6 Problems hour. What would be the LOS before and after the heavy vehicles are allowed on the upgrade (assuming 50% SUTs and 50% TTs.)? 6.21 A multilane highway has four lanes (two lanes in each direction) and a measured FFS of 55 mi/h. The directional peak-hour volume is 1900 vehicles (the peak-hour factor is 0.80). One upgrade is 5% and is 0.62 mi long. Currently, heavy vehicles are not permitted on the highway, but local authorities are considering allowing heavy vehicles on this upgrade. If this is done, they estimate that 150 heavy vehicles will use…
